Magnetic Proximity Sensor

What is the magnetic proximity sensor?

The magnetic proximity sensor is a line switching device that uses magnetic field signals for control, also known as a magnetron switch. Commonly used magnetic switches are available in single- and double-contact.

There are several kinds of magnets, such as rubber magnets, permanent magnet ferrite, sintered neodymium iron boron, etc., which are commonly used on the market. The switch is the reed switch.

When a magnetic substance near the glass tube, under the action of the magnetic field magnetic line, the two reeds in the tube are magnetized and attracted to each other to contact, the reeds will be absorbed together degree, so that the node connected to the circuit connected. When the external magnetic force disappears, the two reeds are separated by their own elasticity and the line is broken.

How does this magnetic proximity sensor work?

The detector of the magnetic proximity sensor is a magnetic probe. When a magnetic probe works, it forms a static magnetic field around it. When an object made of ferromagnetic metal enters into this static magnetic field, a new magnetic field will be induced, which interferes with the original static magnetic field, due to the disturbance caused by the change of target motion, the magnetic field changes, causing the deflection and Oscillation of the magnetometer pointer to produce an electric signal.
